TLC485 converts RS-232 into RS-485 signals. All are port powered and feature automaticsend data control. SDC automatically enables the RS-485 driver when data ispresent on the RS-232 side. Control of the driver is automatic at rates up to 15.2kbps. It is used widely in the field of electricity, industrial automatic controland IC card billing system. It is a high quality, economical data interface conversionproduct.Features:1) Plug and play, small volume, easy installation2) Convert RS-232 data transmit (TXD) and data receive (RXD) signal into balancehalf duplex RS-485 signals3) Powered from RS-232 handshake lines - no power supply needed4) Point to multiple points 5) Automatic send data control - no software drivers needed Specifications: 1) Standard: EIA RS-232, RS-485 standard2) RS-232 signal: TX, RX, GND 3) RS-485 signal: D +, D-, GND4) Working: asynchronism, point to point or multi point, 2 wire half-duplex5) Direction: automatic send data control, auto distinguish and sense direction adoptdata transfer6) Band rate: 300-115, 200bps, auto sense serial signal rate7) Loading: support 32 point loopback (can order 128 points)8) Transmission: RS-485 side 1, 200M (9, 600bps), RS-232 side less than 5m9) Port protection: 600W surge protection, 15KV static protection10) Interface style: RS-232 side DB-9 female, RS-485 side 4 terminal blocks 11) Operating temperature: -40 to 80癈12) Storage temperature: -40 to 85癈13) Relative humidity: 5% to 95%14) Input powered: no power supply needed, powered from TXD, RTS and DTR signal inRS-232 port15) Consumption: static consumption less than 10mA, dynamic consumption less than40mA 16) Dimensions (L x W x H): 90 x 33 x 16.5mm17) Shell: plastic 18) Color: white 19) Weight: 40g producing area:China payment:T/T supplying capacity:100,000pcs/month
